Struct Scanner

pub struct Scanner<'d, C: Controller> { /* private fields */ }

A scanner that wraps a central to provide additional functionality around BLE scanning.

The buffer size can be tuned if in a noisy environment that returns a lot of results.

Implementations

impl<'d, C: Controller> Scanner<'d, C>

pub fn new(central: Central<'d, C>) -> Self

Create a new scanner with the provided central.

pub fn into_inner(self) -> Central<'d, C>

Retrieve the underlying central

pub async fn scan_ext( &mut self, config: &ScanConfig<'_>, ) -> Result<ScanSession<'_, true>, BleHostError<C::Error>>

where C: ControllerCmdSync<LeSetExtScanEnable> + ControllerCmdSync<LeSetExtScanParams> + ControllerCmdSync<LeClearFilterAcceptList> + ControllerCmdSync<LeAddDeviceToFilterAcceptList>,

Performs an extended BLE scan, return a report for discovering peripherals.

Scan is stopped when a report is received. Call this method repeatedly to continue scanning.
